Q: When and how should a GRIB file be updated?

You may have noticed a small icon on the right of each item in the GRIB files list . This icon shows the update status of your GRIB file and can display three different states : 1. Dark orange “Refresh” icon — file up to date The icon appears in dark orange right after a GRIB file has been downloaded. This means your file is up to date — you already have the latest available version of the weather model. This is what you will see immediately after downloading a GRIB file. 2. Light orange “Refresh” icon — new run available The icon turns light orange . This means a new model run (a new forecast) is available. To update your GRIB file, simply click or tap on this icon : the file will automatically be replaced with the latest version. 3. Light orange icon with a download symbol — file missing on this device Finally, the icon may appear in light orange with a small download symbol . This means you have already downloaded this GRIB file on another device , but it is not yet available locally on the one you are using. To retrieve it, simply click or tap on the icon : the file will be downloaded automatically.

Question 3

How do I receive NMEA data from my boat instruments?

Henri · Accepted Answer

Receiving NMEA Data

To receive NMEA data from your onboard instruments:

First, make sure you are connected to the Wi-Fi network of your NMEA server or repeater (MiniPlex, NKE Wi-Fi box, etc.).
Open the Settings panel at the top right (gear icon).
Select the GPS & NMEA menu.

GPS Source

The first line corresponds to the GPS source. If you want to receive GPS data through an NMEA stream, select NMEA.

NMEA Source

NMEA Protocol — preferably UDP, or TCP if required.
IP Address — the IP of your NMEA server or repeater (MiniPlex, NKE Wi-Fi box, etc.).
Port — the port number used by your NMEA source.

If you don’t know these values, press Scan for NMEA Streams. The scan will automatically search for known configurations. When a stream is detected, NavimetriX will offer to apply the parameters automatically (protocol, IP, port). Select Yes and close the scanner — your NMEA source is now active!

Once connected, NMEA data appears in green in the log window at the bottom of the panel.

If no stream is found, enter your NMEA system parameters manually. We recommend using the UDP protocol for maximum flexibility.

NMEA Log

The last section lets you enable NMEA logging. When enabled, all received NMEA sentences are recorded. You can set a retention period (for example, 8 days) and specify when the logs should be compressed. Uncompressed daily files can be large (around 60 MB), but once compressed, they are only about 10% of their original size.

The Export Logs button allows you to save these files for analysis or replay with external tools such as VDR Player.

Note: A built-in feature to replay NMEA logs will be added in a future version of the app.

You may have noticed a small icon on the right of each item in the GRIB files list. This icon shows the update status of your GRIB file and can display three different states:

1. Dark orange “Refresh” icon — file up to date

The icon appears in dark orange right after a GRIB file has been downloaded. This means your file is up to date — you already have the latest available version of the weather model.
This is what you will see immediately after downloading a GRIB file.

2. Light orange “Refresh” icon — new run available

The icon turns light orange. This means a new model run (a new forecast) is available. To update your GRIB file, simply click or tap on this icon: the file will automatically be replaced with the latest version.

3. Light orange icon with a download symbol — file missing on this device

Finally, the icon may appear in light orange with a small download symbol. This means you have already downloaded this GRIB file on another device, but it is not yet available locally on the one you are using. To retrieve it, simply click or tap on the icon: the file will be downloaded automatically.
